You went on a blind date and presented an A-level wanted criminal as a meeting gift?

The next morning, at exactly seven o'clock.

The Yip Group's suburban R&D base has three underground floors.

This is Ye's highest-level materials laboratory, which is usually responsible for the core research and development of new energy battery arrays.

The security level is even higher than that of a bank vault, with triple verification of iris, palm print, and voiceprint. Even Ye Qingcheng herself had to go through the entire process to enter.

Lin Chen took ten seconds.

When the laboratory door opened, Ye Qingcheng had already been waiting inside for half an hour.

She was wearing a fitted white shirt with the sleeves rolled up to her elbows.

Behind him, various pieces of equipment were neatly arranged on the operating table: electron beam evaporation coating machine, nanoscale hot press, molecular beam epitaxy growth furnace, carbon nanotube stretching machine... all top-of-the-line equipment worth hundreds of millions.

"You've come at the perfect time."

Ye Qingcheng pushed a cup of coffee in front of Lin Chen.

"I shut down all ongoing commercial projects last night, so you can use these facilities today."

Lin Chen took the coffee, took a sip, and glanced around the entire laboratory.

In his field of vision, the performance parameters, accuracy limits, and operational range of each device automatically appeared.

The perception brought by the [God-level Materials Science Mastery] was far stronger than he had expected.

Those raw materials displayed on the shelves—carbon nanotube films, graphene aerogels, rare earth permanent magnet powders, non-Newtonian fluid suspensions—are just a bunch of chemicals in other people's eyes.

In Lin Chen's eyes, they were building blocks.

"I need two things."

Lin Chen took off his coat and threw it on the chair, then walked directly to the control panel.

"First, it is a close-fitting bulletproof bra that is light, thin, and discreet, and cannot be seen under normal clothing."

"Secondly, two rings."

Ye Qingcheng raised an eyebrow.

"I understand bulletproof underwear, but what's the ring?"

You'll find out in a minute.

Lin Chen didn't explain further.

He rolled up his sleeves and began operating the machine.

First is bulletproof underwear.

Traditional bulletproof vests use Kevlar fiber laminates or ceramic plates, which are thick, hard, and heavy, making them feel like carrying a door panel on your back.

But what Lin Chen had to do was completely different.

He took three things off the shelf: a carbon nanotube film, a bio-based non-Newtonian fluid suspension, and a roll of spider silk protein fiber.

Dr. Zhang, Ye Qingcheng's chief scientist, watched from the side, becoming more and more confused.

"Mr. Lin, carbon nanotubes and spider silk are not the same type of material; their molecular interfacial bonding forces..."

"Who told you to combine them directly?"

Lin Chen didn't even look up; his hand movements were as precise as a machine.

He first used a molecular beam epitaxy furnace to grow a transition layer only a few hundred nanometers thick on the surface of the carbon nanotube film.

The components of this transition layer were prepared on-site by Lin Chen, using three rare earth elements as catalytic bridging.

Then, spider silk fibers are woven into a mesh-like substrate and placed over the transition layer.

In the final crucial step, he injected a non-Newtonian fluid suspension into the interlayer space between the carbon nanotubes and the spider silk protein.

The characteristics of non-Newtonian fluids are: they are as soft as water when subjected to slow force, and solidify into steel instantly when subjected to high-speed impact.

The three layers stacked together create an unprecedented composite effect.

Under normal conditions, this material is as soft as cotton and can be worn close to the skin without any foreign body sensation.

However, when the bullet impacts at a speed of hundreds of meters per second, the carbon nanotube film provides the first layer of hardness interception, the instantaneous solidification of the non-Newtonian fluid provides the second layer of energy diffusion, and the spider silk protein fiber provides the third layer of toughness buffer.

Three layers of linkage, with each layer decreasing in intensity.

With the added benefit of the system's passive skill [Intermediate Body Armor], it can theoretically withstand close-range shooting from a large-caliber sniper rifle.

Dr. Zhang stood by and watched the whole thing, his forehead constantly covered in sweat.

Having worked in the field of materials science for twenty years, he felt as if he were watching alien technology.

Lin Chen operated the machine for nearly an hour and a half before finally taking the finished product out of the hot press.

It was an extremely thin black bodysuit, weighing less than 300 grams, and felt almost identical to a regular sports quick-drying shirt.

Lin Chen picked it up and looked at it under the light.

Thin as a cicada's wing, yet every fiber contains the power to shatter a bullet.

"this……"

Dr. Zhang's mouth remained open for a long time.

"If this were to go into mass production, it would completely revolutionize the global bulletproof equipment market!"

"We'll talk about mass production later."

Lin Chen folded the bulletproof underwear and started making the second thing.

Two rings.

He used a miniature precision lathe and an electromagnetic coil winding machine from the laboratory.

The ring's outer shell is made of titanium alloy, and it integrates a miniature supercapacitor and a set of high-density electromagnetic coils inside.

After charging, pressing a tiny trigger point on the ring surface can release a high-intensity electromagnetic pulse within a radius of two meters.

This pulse will not harm people, but it is enough to instantly burn out all electronic devices within a two-meter radius, including cell phones, surveillance cameras, eavesdropping devices, and even electronic sights.

In a critical moment, a ring can be a miniature EMP bomb.

It took exactly two hours to build all of this.

Lin Chen flexed his fingers and put the two rings on the ring fingers of his left and right hands respectively.

Ye Qingcheng stood by and watched the whole thing from beginning to end.

She herself is a business elite and has witnessed the operations of countless top scientists.

But what Lin Chen showed today is no longer at the level of a scientist.

This means that the third eye has been opened.

"husband."

Ye Qingcheng walked up to Lin Chen and reached out to straighten his cuffs.

"If you ever quit being a criminal investigation consultant, come to Ye's company as the Chief Technology Officer. You can name your own salary."

"Will you support me?"

"I'll take care of you."

Ye Qingcheng didn't even blink when she said those two words.

Lin Chen smiled, put his arm around her waist, and pulled her closer.

"Qingcheng, guard the rear. You can handle the affairs of Jiangcheng City yourself. Tianqiong Group can no longer cause trouble in the south."

"I know."

Ye Qingcheng looked up at him.

"Go to the capital and do what you're supposed to do. You don't need to worry about money or logistics."

Lin Chen lowered his head and kissed her.

"The 'Alluring City' will be on standby at the international airport at 3 p.m.

After he loosened his grip, Ye Qingcheng added a sentence, her voice regaining the coldness and hardness of the Ye family head.

But the base of her ears was red.
